The SID filed the request with the Taipei District Court yesterday over concerns of collusion and destruction of evidence, SID spokesperson Chen Hung-ta (陳宏達) said.

More time is needed for the SID to conduct its investigation and identify accomplices in the case, Chen said.

The SID submitted its application along with related documents to the Taipei District Court, which is expected to make a ruling shortly. It also requested that Lin, who allegedly took bribes from a metal recycling company, not be allowed to meet anyone.

The SID says there are other likely accomplices in the corruption case who have yet to surface and that Lin was suspected of working together with witnesses and the defendant as well as destroying evidence.

A ruling by the court will further detain Lin from Sept. 1 through Oct. 31.

Lin, who has admitted to taking bribes of at least NT$63 million (US$2.1 million) from a subsidiary company of China Steel Corp, was detained on July 2.

Chen said that while Lin had admitted accepting bribes, investigators were still trying to make breakthroughs on several key developments of the case as well as establishing where the money went.

The spokesperson added that the SID subpoenaed CSC chairman Tsou Juo-chi (鄒若齊) to testify yesterday for the first time as a witness.
